JOHN JOSEPH BERRIGAN, OF ORANGE, NEW JERSEY, ASSIGNOR TO THE DE LAVAL SEPARATOR COMPANY, A CORPORATION OF NEW JERSEY.

SPECIFICATION forming part of Letters Patent No. 775,510, dated November 22, 1904.

Application filed June 3, 1904. Serial No. 210,970.

To all whom it nutyconccrn:

Be it known that I, JOHN J OSEPH BERRIGAN, a citizen of the United States,- residing at Orange, county of Essex, and State of New Jersey, have invented a new and useful Improvement in Discharge-Regulating Devices for Separators, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form apart of this application.

The object of my invention is to regulate and vary during the revolution of the bowl the discharge from the bowl, so that cream or milk of the desired and varied constituency may be obtained without stopping the bowl to obtain such regulation. Speaking generally, I accomplish this object by providing a discharge-tube passing through and to the interior of the bowl and loosely mounted, so as to be capable of moving inward toward the center and outward from the center, the latter movement being produced by and the former movement being against the action of centrifugal force. Preferably I provide in addition to the regular discharge-tube which is secured in the bowl a second tube loosely placed within the discharge-tube,- so as to be capable of moving beyond the inner end of the regular tube, and thus project farther in the liquid-space of the bowl. tube is so loose that the action of centrifugal force will force it to its most outward position. I also provide mechanism which may be operated while the bowl is rotating, which when operated will move the loosely-mounted tube inward against the centrifugal force the desired distance and hold it there and which also will limit and allowvariance in the outward movement of this loosely-mounted tube. I preferably use as a part of the operating means for the movement of this inner tube a ring mounted in connection with the neck of the bowl, so as to have a floating fit thereon, made slightly heavier at one part, so that it is by centrifugal force held in rotative contact.

I have also various details of construction which enable my invention to be readily applied to bowls in use without returning them The fit of the inner (N0 model.)

to the shop for reconstruction and make its use most practical.

I will first describe the embodiment of my invention illustrated in the accompanying drawings and then point out the invention in the claims.

In the drawings, Figure 1 is a side elevation of the device, partly in section. Fig. 2 is a front elevation of the device. Fig. 3 is a side elevation, partly in section. Fig. 4 is a plan of detail. Fig. 5 is a section on line 5 5, Fig. 3.

A is the rotatable bowl, rotated by any wellknown mechanism; B, the neck thereof. The cream-outlet, as shown, consists of the tube O, screw-threaded at its end and secured in a threaded orifice in the neck of the bowl. Within this tube C is a second tube O, fitting loosely therein and having pins 0 projecting through slots 0 in the tube O. As may be seen, the tube O can'freely move longitudinally within the tube O to the limit of the slots 0. When in its outer position, its inner end is substantially in alinement with the inner end of tube C, and when in its inner position it projects within-the bowl beyond the inner end of the tube O. The fit of the tube O within the tube O is such that unless restrained the action of centrifugal force in the operation of the machine will force and hold the inner tube in its most outward position.

D is a ring fitting loosely around the neck of the bowl and having the flange cl at its upper portion. One portion of the ring is cut away at D, and secured thereto or formed therewith at this point is the projecting piece E, having the inclined inner portions 6 c, at the bottom of which are the pins 6 e. The tube O projects through the cutaway portion of the ring D, and the pins 0 0 rest against the inclined portions e c of the piece E. The ring D is provided with the attached strip E, which is of slightly less weight than the piece E, so that in the rotation of the bowl the slight overbalancing of the ring at portion E will cause the ring to slightly bind on and rotate with the neck. In

practice, by means of the piece E, l can readily adjust this balancing or overbala'nc'ing so that the proper contact of the ring and neck for operation may be obtained, and I can do this readily in the field. Indeed, to obtain the correct condition I can readily use ordinary solder for the piece E, applying a sufiicient amount to obtain the desired weight. The arrangement is such that when the ring is in the position that the pins 0 c are on the upper end of incline e the inner tube C will be extended inwardly to its full extent. By lifting the ring the inclines 6 will fall away from the pins; but the centrifugal force will cause the tube C to move in the tube C until the pins contact with the inclines e. The machine is such that at the bottom the inner tube C will move in the tube 0 until its inner end substantially coincides with the inner end of tube (1 It may also be seen that while the bowl is in operation the pins 0 c coacting with pins 1/ a will prevent the ring being lifted off; but when the machine is at rest if the ring he moved down face inward the tube C to its full extent and then moved up the inner tube, being no longer under centrifu gal action, will remain at its most extended position, so that when it reaches the bottom of the inclines e e the pins 0 0 will be beyond pins 6' e and the ring may readily be removed. As may be seen, with this device the ring in one direction extends the inner tube beyond the outer tube a distance dependent upon the extent of movement of ring. In the other direction the ring in its movement limits the return movement of the tube under the action of centrifugal force.

I operate this ring during the rotation of the machine as follows: I is a rod having at its lower end the projecting rollers 2" t the space between which is slightly greater thanthe thickness of the flange cl of the ring D. The upper portion of this rod has the thread cut thereon and working thereon the internally-threaded nut f. Above and below this nut t' and surrounding the rod are the bearings J, secured to the feed-cup Gr. Any other non-rotatable portion of the machine will answer as well as the feed-cup G to which to secure the bearings J. Near the upper end of the rod I is the projecting rod K. The position of the parts, as shown, is such that by moving the rod K the rollers't' and i will be brought, respectively, above and below the flange a. When in this position, by turning the nut 71* in one direction the rod I is elevated, and through the medium of the roller 2' the ring E is elevated and the density of the cream increased, and when the nut is turned in the other direction, through the medium of roller 2', the ring E is depressed and the density of the cream decreased. As the ring E is rotating with the bowl, and thus rapidly, the action of rollerst'and i is practically upon the whole circumference of the flange f of ring Securedto the rod. I isthe pointer M, which when the rod 7 is turned so that rollers 2' i are above and below 'fiange d comes in line with scale m. In the vertical movement of the rod this pointer M travels along the scale, and thus the scale may be graduated, so that the extent of the movement for any given separation of cream may be determined by moving the rod until the pointer indicates on the scale the point corresponding to the position for such separation.
